The Miami Herald's Armando Salguero reports the Miami Dolphins start a mini-camp this Friday and all of Miami's players will attend, according to coach Dave Wannstedt. Some players, including CB Sam Madison, WR O.J. McDuffie and DB Jeff Harris, likely will be limited during the practices because they are still recovering from off-season surgery or injuries. The team will practice once Friday afternoon and twice Saturday and Sunday. The team is also scheduled to conduct a quarterback school next Tuesday, Wednesday and Thursday.
